Many cooking recipes give you the instruction of adding salt
to the water when boiling something. This can do many things
to the water and there must be a special reason why they tell
you to add salt to the water. This experiment will show us how
salt affects the temperature of boiling water.

Hypothesis:

Adding table salt to boiling water will cause the water to
boil at a higher temperature.

1. Boil one quart of distilled water on a stove.
2. Measure the temperature of the boiling water. Record the highest
temperature reading.
3. Measure out table salt using a kitchen measuring spoon. Level
the spoonful.
4. Add the measured salt to the boiling water and stir.
5. Measure the temperature of the boiling water with the salt
in it. Record the highest temperature reading.
6. Repeat it now with two spoons of salt.
